Weight loss injections have gained significant popularity recently, especially after numerous celebrities like Elon Musk and Oprah Winfrey shared their successful experiences with them. This type of injection works by reducing hunger and appetite, which leads to calorie consumption and weight loss. Although nearly all types share the same goal, the active ingredients may vary from one type to another. Here are some types and their mechanisms of action:
**Ozempic**
Ozempic can be considered one of the most famous weight loss brands. It was originally designed to treat type 2 diabetes before scientists discovered it causes weight loss. It contains an active ingredient called "semaglutide," which helps to reduce appetite.
**Wegovy**
Wegovy also contains "semaglutide." It works by mimicking the action of the GLP-1 hormone, which is released after eating and helps create a feeling of fullness.
**Mounjaro**
Its active ingredient is called "tirzepatide." It was initially developed as a treatment for type 2 diabetes. It helps individuals feel full for longer, making it an effective treatment for obesity when used alongside a healthy diet and regular exercise.
**Saxenda**
Saxenda works by helping the pancreas release the appropriate amount of insulin when blood sugar levels are elevated.
**What Are the Side Effects of Weight Loss Injections?**
A review in 2017 noted that the side effects of the dosage tend to be gastrointestinal. This can include nausea, diarrhea, stomach pain, and constipation. Other side effects may be more severe and lead to long-term complications.
